Specification of Letters Patent.

Patented Sept. 25, 1917.

Application filed. .Fe bruary 26, 1917. Serial No. 151,027.

justable go-cart and has for its primary object to provide means forvertically adjusting the body of the cart to an elevated position abovethe wheel supported frame.

It-is another and more particular object of my invention to provide ago-cart having a fixed body section and a vertically movable bodysection, a plurality of links connecting the opposite ends of the latterbody section to the frame, and manually operable means to actuate saidlinks and raise or lower said body sections.

It is a further general object ofmy invention to improve and simplifythe construction of vehicles of the above character whereby the same arerendered highly serviceable and convenient in practical-use, durable inconstruction, and capable of manufacture at relativelysmall cost.

With the above and other objects in view, my invention consists in thenovel features of construction, combination and arrangement of parts tobe hereinafter more fully described, claimed and illustrated in theaccompanying drawings, in which,

Figure 1 is a side elevation of a go-cart or perambulator showing themovable body section in its lowered position;

Fig. 2 is a similar view showing said body section raised or elevatedand the hood extended;

Fig. 3 is an end elevation;

Fig. 4 is a perspective view dog; and I V Fig. 5 is a detail sectiontaken on the line 5-5 of Fig. 1.

Referring in detail to the drawing, 5 indicates spaced channel barswhich constitute the longitudinal side Walls of a frame, and betweenthese channel bars, at one of their ends the transverse brace bar 6 isengaged and rigidly secured thereto by bolts or other similar fasteningdevices. At their opposite ends, the bars 5 are also connected to eachother by a crossbar 7, the ends of which are angularly extended, as at8, and disposed against'the outer side of'the'frame of the rack bars 5.The lower ends of the vertical portions of a suitable handle 9 aredisposed against the inner sides of the bars 5, and said handle securedto the bars 5 and the ends 8 of the cross bar by the bolts indicated at10.

To the under side of each of the frame rails 5, the spring bars 11 arearranged in spaced relation to each other and rigidly fixed at one oftheir ends to said rails. In

loops or eyes 12 formed upon the free ends of the corresponding bars 11,the axles 13 are mounted, and upon the extremities of each axle theground wheels 14 are supported.

Between the forward ends of the rails 5, a fixed body section 15 isarranged, said body section being rigidly secured to the rails by meansof suitable bolts indicated at 16.

Spaced rods or shafts 17 'and 18 respectively, aremounted at their endsin the frame bars 5. The rod or shaft 18 is rotatably supported, andupon the same, adjacent its ends, the lower ends of links 19 are looselyengaged. A second pair of links 20 are also fixed at their lower endsupon this shaft. Similar links 21 are loosely mountedupon the ends ofthe shaft 17. The upper ends of the links 20 and 21 are pivot-ally connected to the relatively opposite ends of a rectangular frame bar 22. 23designates angle bars upon'which the angular flanges 25 on the loweredges of the side walls 24: of a vertically movable body section, aremounted and secured. The floor or base 26 of this movable section of thebody is also secured to these angle bars. Links 27 and 28 are pivotallyconnected at their upper ends to the relatively opposite ends of each ofthe angle bars 23. The lower ends of the links 27 and the upper ends ofthe links 19 are connected to each other by bolts-29 which are looselyengaged for longitudinal movement in slots 30 provided in thelongitudinal portions of the frame bar 22. Links 20 also have theirupper ends engaged upon the pivots of the link 27 connecting the same tothe angle bars 23 and the'lower ends of the links 20 and the upperendsof the links 20 are connected to the frame 22 by the pivot bolts 20 Thelower ends of the links 28 and the upper ends of the links 21 arepivotally connected to one end of .the bar 22 by the bolts 31. The sidewalls 24 of the movable body section are cut away at one of their ends,as indicated at 32, and provided with upwardly and rearwardly curved,attenuated portions 33 A sector-shaped hood 3th is pivotally mountedupon the rear ends of the angle bars 23, as shown at 35, and the sidewalls of this hood are each provided with t $1.01 3.6 extending. inconcentric relation to the pivot 35. Bolts or guide pins 37 fixed in theextensions 33 of the side walls re nga d the e slotsbie e of he sh ft. 3a lever 3 i fixed, and to said lever adjacent its other end, one end ofa curved rack bar 39 is'se- Cured, the t et .0. sa r be g d pted toco-act with the tooth or point 41 ofa locking dog 42. The end of thislocking dog is cut away-or recessed on one face as at 4 3, and the rackbar 39 moves between this recessed face and the adjacent fran e bar 5.The dog 42 is pivotally' mounted upon a stud bolt tt'fixed in the framebar 5. Adjacent to the dog i2, asubstantially triangulara shaped plate45 is pivotally mounted in the bar 5, as at 46. One end of a short rod4]? is loosely connected to this plate and the other end thereof is p otl y' c n ec e to. t dos L s 2 h In the operation of the device as abovedescribed, when it is desired to elevate the ovabl b s et of h ar i e orgo? cart from the position shoWnin-F gl 1 to the position shown Fig. 2,the lever 3,8,. is or ed f rwar y n downwardly, ere by ai n t e ink jwd. p n t e shaf 18 and also forcing the frame 22 upwardly.

The 19. an d'27' will thus be spread apart as wellas the links 21and' 28so that the movable body section will be raised above the frame 22 bythe links 27 and 28,

The links 20, and 20! are moved slightly past the perpendicular and atan opposite.

ang Wi h resp c to he links 1 M 127, t

Seen inFig; 2- Wheri the lever is in substantially horizontal position,the movable body section will have, been raised or elevated to, its fullextent, and the dog 42- will engage the teeth of the rack bar '39 to.sustain the body section in its elevated. Position When it is desired tolower the m ovable body section, the end of the lever 38.

is depressed slightly and the plate 45. moved to withdraw h t e of hclog 2 rom engagement with the rack teeth 40. The movement of the leveris. then reversedso.

that the pairs of linksIlQ. and 27, and 20, andQQ, are, folded upon eachotherin relatively opposite. directiqns and he frame 22: and the movablsection'of the vehicle body lowered; upon the wheel supported. frame.

To ea ch of the sidewalls 24 a stud. bolt 49 is fixed; and upon these,stud bolts, arms 50 are b' e y olll fi li a e Qt en s nd adapted to besecurely clamped'in ad. iustable, tast r PQ L Qll y i a l nuts.

of said bars. Links 5,4 pivotally connected to each other as at 55,connect the arms 50 and 53, whereby the arms 53 may be folded relativeto the arm 50.
